Options
- AA-1; B-2; C-3; D-4
- BA-2; B-3; C-1; D-4
- CA-2; B-1; C-4; D-3
- DA-2; B-1; C-3; D-4
Correct answer
D. A-2; B-1; C-3; D-4
Step-by-step solution
Arteries have thick elastic walls to withstand high pressure. Veins have thin walls with valves to prevent backflow. Capillaries are microscopic and one-cell thick, allowing for exchange of materials. Venules connect capillaries to veins.
